GRINDING, PULPING, AND PULVERIZING MACHINE.

To all whom it may concern:

Be it known that I, HAROLD JACKSON, a British subject, residing atGarstang, county of Lancaster, England, havelwinvented certain new anduseful Improvements in Grinding, Pulping, and Pulverizing Machines, ofwhich the following is a specification.

This invention relates to apparatus for pulping, pulverizing orsimilarly treating substances such as fibers for paper pulp, requiringto be finely ground or pulped in a wet or semi-liquid state. i

It consists essentially of a machine where- 111 the pulp is subjected toa compound mechanical treatment comprising a combined vibratory tappingor hammering and a rubbing or dragging action between a ribbed surfaceand relatively movable boaters.

In the accompanying drawing :--Figure 1 is a side elevationof theimproved machine; Fig. 2 is a plan view thereof; Fig. 3 is a sideelevation of a similar machine set inclined; Fig. 4 is a side elevationof a similar machine set horizontal; Fig. 5 is an enlarged verticalsect-ion of part of the machine; Fig. 6 is a transverse section on linea"a:, Fig. 5;

Fig. 7 is a transverse section on line z y,'

Fig. 5; Fig. 8 is a sectional elevation showing spiral ribs; Figs. 9 and10 are, respectively, a side elevation and a plan view of one form ofheater; and Figs. 11 to 16 are corresponding views of other forms ofbeaters.

' The machine is constructed with a rotor A and a casing B, comprisingcomplemental parts, one of which is provided with movable heaters C andthe other with coacting ribs or projections D.

The beaters C are affixedradially or tangentially to the part by whichthey are carried, in the present instance, the rotor, and may bearranged in rows or spirally. They are preferably pivoted to such part,and may be in the form of blades with fiat, or hammer-shaped ends, asshown in Figs. 5, 6, 9 and 10, or of swinging arms provided with rollersC, as in Figs. 11 and 12, or of links or flat blades C as in Figs. 13and 14, or of solid blocks Ct, as in Figs. 15 and 16.

The part with which the heaters coact is "provided with theaforementioned ribs or projections D. These ribs or projections areSpecification of Letters Patent.

set closely together, and. may be arranged either parallel to thelongitudinal axis of the part whereon they are provided, as in Fig. 5,or spirally around it, as in Fig. 8, or in any other desired manner.

The rotor may be fitted with a screw propeller D to force the materialthrough the casing, and the latter may be provided, in turn, withinclined vanes or blades E which also assist in conveying the materialupward or forward as it is carried around by the boaters. Thesemi-liquid material may be circulated through the casing by means of asuitable pump, or the like, and may be caused to pass from said easinginto a hopper G, and thence back into the casing.

The apparatus may be arranged vertically, as in Figs. 1 and 5, or it maybe either inclined, as in Fig. 3, or horizontally arranged as in Fig. 4.The rotor is run at a speed which is most suitable for the semi-liquidmaterial being treated, and it produces a compound mechanical treatmentof the fibers comprising a. simultaneously exerted or combined gentlehammering or tapping and a rubbing or dragging act-ion, as the heaterssuccessively jump from one rib or projection to the next.

I claim as my invention 1. Apparatus for finally treating ground paperpulp consisting of a casing, and a rotor revoluble therein and having aplurality of beaters pivotally connected thereto, said heaters beingoperable by centrifugal force to act direct-lytagainst the sides of thecasing.

52. Apparatus for finally treating ground paper pulp consisting of acasing, and a rotor revoluble therein, said casing and rotorconstituting companion parts, one of which parts is provided with aseries of pivotally mounted heaters operable by centrifugal force to actdirectly against the adjacent surface of the other part.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

HAROLD JACKSON.
